Static Electricity Precautions
It is quite easy to inadvertently damage your PC, system board, components
or devices even before installing them in your system unit. Static electrical dis-
charge can damage computer components without causing any signs of physical
damage. You must take extra care in handling them to ensure against electro-
static build-up.
1. To prevent electrostatic build-up, leave the system board in its anti-static bag
until you are ready to install it.
2. Wear an antistatic wrist strap.
3. Do all preparation work on a static-free surface.
4. Hold the device only by its edges. Be careful not to touch any of the compo-
nents, contacts or connections.
5. Avoid touching the pins or contacts on all modules and connectors. Hold
modules or connectors by their ends.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and
other components. Perform the upgrade instruction procedures described
at an ESD workstation only. If such a station is not available, you can
provide some ESD protection by wearing an antistatic wrist strap and
attaching it to a metal part of the system chassis. If a wrist strap is
unavailable, establish and maintain contact with the system chassis
throughout any procedures requiring ESD protection.

Introduction
Features
Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the sys-
tem at the set time interval. If the system hangs or fails to function, it will reset
at the set time interval so that your system will continue to operate.
DDR3
DDR3 delivers increased system bandwidth and improved performance. It offers
peak data transfer rate of up to 21 Gb/s bandwidth. The advantages of DDR3
are its higher bandwidth and its increase in performance at a lower power than
DDR2.
Graphics
The Intel northbridge chip comes integrated with the Intel Graphics Media Accel-
erator X4500 delivering 3D, 2D and video capabilities. With support for Microsoft
DirectX 10 and OpenGL 2.1, Intel GMA X4500 delivers excellent video and 3D
graphics with outstanding graphics responsiveness. These enhancements deliver
the performance and compatibility needed for today’s and tomorrow’s business
applications.
PCI Express
PCI Express is a high bandwidth I/O infrastructure that possesses the ability to
scale speeds by forming multiple lanes. The x1 PCI Express lane supports trans-
fer rate of 2.5 Gigabytes (250MBbps) per second.
Audio
The Realtek ALC662 audio codec provides 6-channel audio output for advanced
5.1-channel super surround sound audio system.
Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification.
With speed of up to 3Gbps, it improves hard drive performance faster than the
standard parallel ATA whose data transfer rate is 100MB/s.
Gigabit LAN
The two Realtek RTL8111DL PCI Express Gigabit controllers support up to 1Gbps
data transmission.

13
Introduction
USB
The system board supports USB 2.0 and USB 1.1 ports. USB 1.1 supports 12Mb/
second bandwidth while USB 2.0 supports 480Mb/second bandwidth providing a
marked improvement in device transfer speeds between your computer and a
wide range of simultaneously accessible external Plug and Play peripherals.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft Power Off
mode to wake-up/power-on to respond to calls coming from an external modem
or respond to calls from a modem PCI card that uses the PCI PME (Power Man-
agement Event) signal to remotely wake up the PC.
Important:
The 5V_standby power source of your power supply must support
≥720mA.
Wake-On-LAN
This feature allows the network to remotely wake up a Soft Power Down (Soft-
Off) PC. It is supported via the onboard LAN port or via a PCI LAN card that uses
the PCI PME (Power Management Event) signal. However, if your system is in the
Suspend mode, you can power-on the system only through an IRQ or DMA inter-
rupt.
Important:
The 5V_standby power source of your power supply must support
≥720mA.
Wake-On-PS/2
This function allows you to use the PS/2 keyboard or PS/2 mouse to power-on
the system.
Important:
The 5V_standby power source of your power supply must support
≥720mA.
Wake-On-USB
This function allows you to use a USB keyboard or USB mouse to wake up a sys-
tem from the S3 (STR - Suspend To RAM) state.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB
ports, the 5V_standby power source of your power supply must support
≥1.5A. For 3 or more USB ports, the 5V_standby power source of your
powersupplymustsupport≥2A.

Introduction
RTC Timer
The RTC installed on the system board allows your system to automatically pow-
er-on on the set date and time.
ACPI STR
The system board is designed to meet the ACPI (Advanced Configuration and
Power Interface) specification. ACPI has energy saving features that enables PCs
to implement Power Management and Plug-and-Play with operating systems that
support OS Direct Power Management. ACPI when enabled in the Power Manage-
ment Setup will allow you to use the Suspend to RAM function.
With the Suspend to RAM function enabled, you can power-off the system at
once by pressing the power button or selecting “Standby” when you shut down
Windows®without having to go through the sometimes tiresome process of
closing files, applications and operating system. This is because the system is
capable of storing all programs and data files during the entire operating session
into RAM (Random Access Memory) when it powers-off. The operating session will
resume exactly where you left off the next time you power-on the system.
Important:
The 5V_standby power source of your power supply must support
≥720mA.
Power Failure Recovery
When power returns after an AC power failure, you may choose to either power-
on the system manually or let the system power-on automatically.
